Besides the Spirit Grass, there were also many cultivators who had lost their direction within, trapped and slowly dying, their storage Magic Artifacts containing many treasures.
Therefore, it attracted quite a few cultivators to come treasure hunting, or to search for Spiritual Medicine.
The reason Lin Yi came here was that within the miasma, a cultivator's Primordial Spirit could not be extended, and the ability to sense was weakened to an extreme, to the point where even searching devices would face great interference. It could be said to be an excellent place for secluded cultivation.
As for the harm of the miasma, he was not at all worried, for his divine abilities were enough to counter the miasma's damage.
After walking out of the Transmission Hall of Green Mist City, he saw many shops selling various miasma protection artifacts around him, some fully enclosed armors, others Miasma Avoidance Pearls, a variety of items.
